From 15280e8107e17a5ee40509e3d1384ad28d6fdcf4 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann <arnd@arndb.de> Date: Wed, 25 Jul 2018 11:18:34 +0200 Subject: sparc64: add reads{b,w,l}/writes{b,w,l} Some drivers need these for compile-testing. On most architectures they come from asm-generic/io.h, but not on sparc64, which has its own definitions. Since we already have ioread*_rep()/iowrite*_rep() that have the same behavior on sparc64 (i.e. all PCI I/O space is memory mapped), we can rename the existing helpers and add macros to define them to the same implementation.
